Slot connector terminal structure for connecting an electrical wire to a part mounted inside a housing

Abstract

A slot connector terminal structure for an electrical wire, in particular for an electrical terminal block, in which structure at least one conductive connector part is held stationary in a housing (5) provided with a wire-insertion through opening (23) extending facing an insulation-displacement and core-retaining slot (6) in the connector part, which opening makes it possible firstly for a wire to be connected to be inserted transversely above the slot, and secondly for the wire to be subsequently held stationary via its sheath, the housing further including positioning means for positioning a special connection tool, which positioning means are implemented in the form of a projecting element through which a moving blade of the tool penetrates. The projecting element is provided with a slot (13) into which the wire-insertion through opening (23) opens, which slot makes it possible for the blade of a tool to penetrate into and slide along the slot inside the housing.

What is claimed is: 
     
       1. In a slot connector terminal structure for an electrical wire (2), and in particular for an electrical terminal block, in which structure at least one conductive connector part (3) is held stationary in an insulating housing (5) provided with a wire-insertion through opening (23) extending facing an insulation-displacement and core-retaining slot (6) for displacing the insulation on and retaining the core of a wire, which slot is assigned to connecting the core of the wire electrically to the connector part, and is provided in a wall of the connector part, said wire-insertion through opening making it possible firstly for a wire to be connected to be inserted transversely above an insulation-displacement entrance (8) of the slot (6) in the connector part, and secondly for the wire to be subsequently held stationary via its insulating sheath (12), the housing (5) further including positioning means for positioning an external connection tool (19) having an insertion blade (18), the positioning means being implemented in the form of a projecting element (14) through which the insertion blade (18) penetrates, which blade is rigid and is mounted to move in translation, so as to slide along the insulation-displacement slot during wire insertion, the improvement wherein said housing includes at least one projecting element provided with a tool-insertion slot (13) which extends the wire-insertion through opening (23) and opens out into one end thereof so as to make it possible firstly for the wire to be inserted into the housing prior to connection, and secondly for the insertion blade of a tool to penetrate into and slide along the slot in the connector part on connection. 
     
     
       2. A slot connector terminal structure for an electrical wire, according to claim 1, wherein said housing is provided with a wire-insertion through opening (23) formed of two portions, a first portion forming a slot for holding the sheath of a wire stationary, which slot is disposed facing the insulation-displacement and core-retaining slot (6) in the connector part, and a second portion making it possible for a wire to be connected to be inserted transversely above the insulation-displacement entrance of the insulation-displacement and core-retaining slot, the improvement further comprising the second portion being itself in the form of a slot which is wider than and extends the slot for holding the sheath of the wire stationary, and which is continued by the tool-insertion slot (13), which extends perpendicular to it.
